fixes #538 setopt should have an explicit chkopt routine
fixes #537 Internal TCP API needs better name separation
fixes #524 Option types should be "typed"
This is a rework of the option management code, to make it both clearer
and to prepare for further work to break up endpoints. This reduces
a certain amount of dead or redundant code, and actually saves cycles
when setting options, as some loops were not terminated that should have
been.

* fixes #419 want to nni_aio_stop without blocking
This actually introduces an nni_aio_close() API that causes
nni_aio_begin to return NNG_ECLOSED, while scheduling a callback
on the AIO to do an NNG_ECLOSED as well. This should be called
in non-blocking close() contexts instead of nni_aio_stop(), and
the cases where we call nni_aio_fini() multiple times are updated
updated to add nni_aio_stop() calls on all "interlinked" aios before
finalizing them.
Furthermore, we call nni_aio_close() as soon as practical in the
close path. This closes an annoying race condition where the
callback from a lower subsystem could wind up rescheduling an
operation that we wanted to abort.

fixes #360 core should nng_aio_begin before nng_aio_finish_error
fixes #361 nng_send_aio should check for NULL message
fixes #362 nni_msgq does not signal pollable on certain events
This adds support for contexts for both sides of the surveyor pattern.
Prior to this commit, the raw mode was completely broken, and there
were numerous other bugs found and fixed. This integration includes
*much* deeper validation of this pattern.
Some changes to the core and other patterns have been made, where it
was obvioius that we could make such improvements. (The obviousness
stemming from the fact that RESPONDENT in particular is very closely
derived from REP.)

This provides context support for REQ and REP sockets.
More discussion around this is in the issue itself.
Optionally we would like to extend this to the surveyor pattern.
Note that we specifically do not support pollable descriptors
for non-default contexts, and the results of using file descriptors
for polling (NNG_OPT_SENDFD and NNG_OPT_RECVFD) is undefined.
In the future, it might be nice to figure out how to factor in
optional use of a message queue for users who want more buffering,
but we think there is little need for this with cooked mode.
